Fix hygene issue when deriving Debug The code for several of the core traits doesn't use hygenic macros. This isn't a problem, except for the Debug trait, which is the only one that uses a variable, named "builder". Variables can't share names with unit structs, so attempting to [derive(Debug)] on any type while a unit struct with the name "builder" was in scope would result in an error. This commit just changes the name of the variable to "__debug_trait_builder", because I couldn't figure out how to get a list of all unit structs in-scope from within the derive expansion function. If someone wants to have a unit struct with the exact name "__debug_trait_builder", they'll just have to do it without a [derive(Debug)]. I also checked the implementations of the other built-in derives to ensure they didn't declare any variables. |
